IMPROVEMENT lN FEEDING DEVICES FQR TICKET-PRINTING PRESSES.

Specification forming part of Letters Patent No. 172,715, dated January :25, 1876; application filed October 7, 1875.

To all whom it may concern:

Be it known that 1, CHARLES WESLEY DIGKINSON, of the city of Newark, county of Essex and State of New Jersey, have invented a new and useful Improvement in Feeding Devices for Ticket-Printing Presses, which improvement is set forth in the following specification, reference being had to the accompanying drawings.

The object of the invention, being a reciprocating feed-motion for presses that print tickets or cards upon strips of paper, is at tained in the manner following:

The strip is placed on a stationary platform, beneath which is a reciprocating slide that has a clamp at each end locking upon the edges of the strip of paper for the forward movement, unlocking and remaining unlocked during the backward movement while the impression is being made.

' Figure l in the drawings is a vertical section through the length of the platform and the reciprocating slide. Fig. 2 is a side view of the machine. Fig. 3 is a transverse sec tion through one of the ends of the reciprocating slide at the dotted line in Figs. 1 and 2; and Fig. at is a top view of the lockingbar.

A is the platform. B is a slide, moving below the platform the distance allowed by the stops 2 and y. In the interior of the slide is shown two spiral springs, X X. Inside the coils a bar, 0, is placed, having at or near its middle arms projecting downward through to the under side of the locking-bar. D. These arms W W form bearings for the circular head of the rocking-lever E, by which motion is communicated to the slide.

The springs X, pressing at each inside end of the slide B, and against the arms W of the bar 0, serve to keep the bar in the middle of theslide while being moved back and forth,

. their peculiar use consisting in allowing a further motion of the lever-bar, when the slide has reached the stop 2 or y, carrying along the locking-bar D at one end of movement,

forcing upward, by the inclines u and t, the clamps s s s s all at one and the same time, and at the other end forcing the inclines from under the clamps, the spiral springs r r forcing the clamps down upon the paper at the edges thereof, to be carried forward by the next motion of thelever E.

It will be seen that bearings 0 are provided,

attached to the ends of the slide B, to allow' of the extra motion l'orlocking the clamps by the bar D.

In Figs. 1 and 2 the position of the slide, and of the locking-bar therein shown, is that of the return of the lever E by the force of the springs X after having unlocked the clamps, the slot min the locking-bar D allowing such return without moving the lockingbar. The slide B and locking-bar are then together carried back upon the paper, for the clamps to be closed upon the edges of the paper, by forcing the inclines a and 25 from under the clamps when the slide has reached the stop 3 A regulating-spring, F, is placed at the enterin g end of the strips of paper, for the purpose of insuring a like beginning of the position of each strip in the printing of the first ticket.

In the end of the slide B an inclined aperture, n, is made, into which the incline h, attached to the under side of the spring, enters, it depressing the spring at the same time as the clamps look upon the edge of the paper.

What I claim is- 1. The platform A, slide B, springs X and r, the bar 0, locking-bar D, and the clamps s, constructed, arranged, and combined as and for the purpose specified and shown.

2. Also, the lever E and the spring F, in combination with the slide and platform, substantially as hereinabove set forth.
